This study deals with the determination of total mercury concentration in the water taken from three sites on Al-Kabeer Al-Shemaly River ( near the industrial area and Al- Damat Lake, and 16 Tishreen Lake), also the effect of some physio-chemical parameters including: DO, pH, T °C. of water in the three sites was studied. Results showed that the total mercury concentration was low in general, where the medium concentration in the three studied sites was 0.29 ppb and it was less than the permission level of total mercury in the surface water(> 10 ppb), the higher value of the medium concentration of total mercury(0.35, 0.31, 0.21)ppb was recorded in the Industrial Area, Damat Lake, then 16 Tishreen Lake, respectively. For the changes in the total concentration of mercury in the three studied sites during seasons of a year, was higher in Summer comparing with other seasons. The results showed positive correlation coefficient between the total mercury concentration and temperature, pH value, but it was negative with DO in Summer.

Research summary
تهدف هذه الدراسة إلى تحديد التركيز الكلي للزئبق في مياه نهر الكبير الشمالي في اللاذقية، سوريا، ودراسة تأثير بعض المتغيرات الفيزيوكيميائية على هذه التراكيز. تم جمع العينات من ثلاثة مواقع مختلفة على طول النهر: قرب المنطقة الصناعية، بحيرة الدامات، وسد 16 تشرين. تم استخدام جهاز الامتصاص الذري وفق تقانة البخار البارد لتحليل العينات. أظهرت النتائج أن التركيز الكلي للزئبق كان منخفضًا بشكل عام في المواقع الثلاثة، حيث بلغ متوسط التركيز 0.29 ppb، وهو أقل بكثير من الحد المسموح به في المياه السطحية (10 ppb). سجلت أعلى قيمة للتركيز الكلي للزئبق في المنطقة الصناعية، تليها بحيرة الدامات، ثم سد 16 تشرين. كما أظهرت الدراسة أن التركيز الكلي للزئبق كان أعلى في فصل الصيف مقارنة ببقية الفصول، مع وجود علاقة ارتباط طردية بين التركيز الكلي للزئبق ودرجة الحرارة ودرجة الحموضة pH، وعلاقة ارتباط عكسية مع تركيز الأكسجين المذاب في الماء DO. توصي الدراسة بضرورة مراقبة تراكيز الزئبق في المياه السطحية ومعالجة مياه الصرف الصحي والصناعي قبل صرفها في الأنهار.
Critical review
دراسة نقدية: تعتبر هذه الدراسة مهمة في مجال تقييم التلوث البيئي، خاصة فيما يتعلق بالزئبق الذي يعد من العناصر المعدنية السامة. ومع ذلك، يمكن توجيه بعض الانتقادات البناءة. أولاً، كان من الممكن توسيع نطاق الدراسة ليشمل المزيد من المواقع على طول النهر للحصول على صورة أكثر شمولية. ثانياً، لم تتطرق الدراسة بشكل كافٍ إلى المصادر المحتملة لتلوث الزئبق في كل موقع، مما يجعل من الصعب تحديد الإجراءات الوقائية المناسبة. ثالثاً، كان من الممكن استخدام تقنيات تحليلية إضافية لتعزيز دقة النتائج. وأخيراً، لم تتناول الدراسة تأثير التلوث بالزئبق على الحياة المائية والنظام البيئي بشكل مفصل، وهو جانب مهم يجب مراعاته في الدراسات المستقبلية.

Al-Kabeer Al-Shemale river rises from Aqraa Mountain and coastal mountains, it is considered one of the largest rivers in the coastal area.Its catchment area is 1097 km2, and empties into the sea to the southern of Lattakia.The study aims to determin e the impact of climate change on the river discharge. Since the rainfall is the major factor in the runoff formation in the river catchment, the rainfall changes have been studied in climatic stations located within the catchment and its surroundings, and for a period of time exceeding thirty years. The study found that the general trend of rainfall change and runoff with time is decreasing, declining rainfall values ranged in the studied stations between (0.4-12.5) mm per year, and the runoff reached 0.08m3/s in the year. A mathematical equation, predict river discharge after knowing the values of daily precipitation, has been concluded.
To clarify the possibility of using bacterial flora as a pollution indicator, water samples from river were collected and analyzed from July ١٩٩٩ to February ٢٠٠١ for dissolved oxygen (DO), NO٣-N, NO٢-N, NH٤-N, PO٤-P, suspended solids (SS), biolog ical oxygen demand (BOD) Heterotrophic Bacteria were identified to genus level, and another part of it was identified to Enterobacteriaceae.
Middle Miocene deposits reveal the form of outcrops which are limited in area on the northern boards of the basin of AL-KABEER Al-Shemaly River. It is characterized by a large and fast changes in thickness and facies. This study focused on the res ults of careful Fossile analysis of 41 samples (hard and soft) which were taken from the three geological sections, through which the principal zones, which characterize middle Miocene, were confirmed depending on planktonic foraminifera. N9, -Orbulina suturalis-Globerotalia peripheroronda N10-N13-Globerotalia fohsi, Sphaaerodinellopsis subdehiscens- Globigrina drury , N14 – Globigerina nepenthes- Globerotalia siakensis. It was identified as benthic foraminifera, which has been characterized by its diversity and their increasing numbers in the northern boards of the Neogene basin and identify the lithology of these deposits consisting of alternations of limestone and limestone of medium hardness to very soft marl with different colors. This study also contributed to the detection of some paleogeographical development in the basin in that period of time.
The lithological study and micropaleontological analyses of 21 samples taken from four geological sections of lower Miocene deposits led to a stratigraphic study for determination of enrichment of planktonic species in these deposits . These speci es were combined with biozones of lower miocene and their stratigraphic distribution in the studied sections according to planktonic foraminifera of worldwide spreading . This study contributed in understanding of paleogeographic development of Neogene basin within this period of time , which appeared as a marine progress in lower Miocene , which continued up to upper Miocene in the northwestern part of Syria . The sediments of lower Miocene consisted of marl , clay marl deposits with interfacial layers of clay and limestones or marl limestones deposited unconformithy with nummoliticlimestones of Eocene , or cretaceous carbonates rich in betome sometimes .
Given to the danger of chemical pollution in general and in Surface water wells in agricultural and populated areas, we carried out a scientific study to measure the existence level of some metal ions in distributed water wells within environment vil lages (SitGers, RuwaysatHarash, Bdmeon) and to monitor changes in their values as an indicator of the rate of chemical pollution in the study area due to existing activities. Research has included analyzes monthly periodical physical chemical to invested wells of villages (SitGers, RuwaysatHarash, Bdmeon) in Lattakia over the full year starting from November 2010 untilOctober 2011 with two wells selected from each village in the study, The study included identification pH , electrical conductivity , temperature and set of negative electrolytes (nitrate NO3-,phosphatePO4-3, sulfateSO4-2) in addition to positive electrolytes (ammoniumNH4+,potassiumK+), The recorded Values for the studied ions varied during the study months to the same wells, due to existing activities, especially the agricultural and climatic conditions that prevailed during the sampling dates. The recorded results show the existence cases of chemical contamination in studied water wells portend a lot of environmental and health risks, especially that most of these wells water used for drinking and irrigation together.
